Abstract (en)
[origin: WO2019204379A1] A detection device (100) includes a detection mat (102) having a plurality of detection coils (106), and at least one pair of groups of detection coils (106), the pair of groups of detection coils (106) includes first and second groups of detection coils (106). The first and second group of detection coils (106) comprises first and second first and second impedance values. The detection device (100) includes one or more drive sub-systems (112) and a comparison sub-system (112). The drive sub-systems (112) are operatively coupled to the detection mat (102) and configured to excite at least one pair of groups of detection coils (106). The comparison sub-system (114) is operatively coupled to the detection mat (102) and configured to receive a differential current signal from the pair of groups of detection coils (106), the comparison sub-system (114) is configured to generate a control signal based on the differential current signal.
